In a Contact Center Enterprise with Cisco Unified Customer Voice Portal and Cisco Unified Border Element deployment, the Cisco Unified Border Element must be configured as media pass flow-through mode. In this mode, the Unified Border Element is configured to route all media traffic directly to the customer voice portal and not through the voice gateway.

Common Ground is a Cisco solution for contact center environments, which enables customers to use multiple channels, such as voice, chat, and email, to interact with agents. Upgrading Common Ground usually involves several steps, including:

Updating the hostname as appropriate: Depending on the configuration and organization of the system, it may be necessary to update the hostname to ensure that all components are properly identified and connected.

Database migration: As part of the upgrade process, the Common Ground database may need to be migrated to a new version or schema. This is done to ensure that the database is compatible with the new version of Common Ground and that all data is preserved during the upgrade.

Updating IP address: Depending on the network and IP addressing scheme, it may be necessary to update the IP addresses of Common Ground components to ensure that they are properly configured and accessible.

Updating registry: Windows registry may need to be updated as well, to ensure that the correct configurations and settings are in place after the upgrade.

In-place upgrades: In-place upgrades are the upgrades that can be done on the same version of the software without the need to install new version of the software.

Two considerations for Active Directory (AD) are that Read-Only Domain Controllers (RODC) are supported and that it supports multi-domain, single AD Forest topology. RODC are used to provide secure access to AD data in remote locations, and the multi-domain, single AD Forest topology allows multiple domains to be managed from a single AD forest. Additionally, global catalogs are required at each AD site to enable efficient searches across the entire AD forest. AD does not provide a user interface, but Remote Access Control is available for software that is used to manage and administer the AD environment.

An AW/HDS machine is a hybrid of an AW client machine and a Secondary AW machine, and it is used to run automated deferred sync jobs. These jobs are typically used to transfer data between two or more AW machines, and the AW/HDS machine acts as the intermediary, making sure that all of the data is kept up-to-date and in sync.
